INDI (Instrument Neutral Distributed Interface) indiserver through 2.2.4.2, fixed in commit 96bbd7f, contains a stack buffer overflow vulnerability that allows unauthenticated remote attackers to crash the daemon by sending malformed XML with mismatched tags whose names exceed 1024 bytes. Attackers can send a single TCP packet on port 7624 with mismatched XML tags to trigger an unbounded sprintf() write into a fixed 1024-byte stack buffer in MsgQueue.cpp, terminating the daemon and disrupting all active client and driver sessions.
AnalysisAI
Remote unauthenticated denial-of-service in INDI indiserver through 2.2.4.2 allows any attacker with TCP access to port 7624 to crash the daemon with a single malformed packet. The vulnerability stems from an unbounded sprintf() call writing XML error messages into a fixed 1024-byte stack buffer in MsgQueue.cpp - sending mismatched XML tags whose names exceed that boundary overflows the stack frame and terminates the process, immediately disconnecting all active astronomical instrument drivers and client sessions. …

Vulnerability AssessmentAI
| Exploitation | The INDI indiserver daemon must be running and accepting connections on TCP port 7624 (the default and standard INDI port). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N scoring 8.7 accurately characterizes the attack profile: fully remote, zero authentication, no user interaction, low attack complexity, and exclusive availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Update INDI to a build incorporating commit 96bbd7f or later from the indilib/indi repository (https://github.com/indilib/indi/commit/96bbd7f564bbb128a129019e44eadd40dd49cff9); as no specific tagged patched release version has been confirmed, monitor the repository for a release announcement. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all systems running INDI indiserver through version 2.2.4.2 and verify network exposure; prioritize any systems accessible from untrusted networks. …
